What is Facebook Debugger?

Facebook Debugger is a tool used to fix errors in post previews on Facebook. These errors can include the blog’s featured image not appearing, the title is incorrect, or the description is incorrect.

Then, how is the process of previewing the share link on Facebook? And why does the preview problem occur?

Previously, let’s take a look at an example of a Facebook preview that will be displayed when you share a blog post on Facebook below:

Now, from the image above, you can tell that a Facebook preview includes several things:

  • Introduction. Introductory sentences for posting on Facebook.
  • Picture. Illustrations and captions taken by Facebook’s crawlers from the blog.
  • Caption. Title and explanation of blog scraping results from blogs.

The problem occurred when the preview of the share link experienced an error. So that either the introduction, image, or caption that appears is inappropriate.

Why is that? Here are some reasons:

1. Caching on Facebook

Facebook uses a 30 day cache system. This means that if you make a content change, the Facebook crawler won’t immediately start looking for updates. As a result, the preview shown when sharing the latest posts is still an old preview.

2. Caching in WordPress

WordPress also has a cache system for speed purposes. However, it is not uncommon for the latest updates on a blog to be stored in the WordPress cache system. So, when posting to Facebook, it’s not uncommon for you to still display previews that haven’t been updated.

3. Missing Featured Image

Regarding the structure of WordPress, the Facebook crawler sometimes doesn’t find the Featured Image used. Finally, crawlers sometimes select other images or even include no images in the preview at all.

4. No Open Graph Meta Tags

Facebook displays a preview of the website according to the results of its crawling. The results may differ from what you expected. Unless you add Open Graph meta tags (og tags) to the website and specify how the preview should be displayed. Usually the SEO plugin that you use will automatically add og tags. For example, Yoast SEO .

5. Image size

Facebook has a requirement for the size of the image displayed, which is a maximum width of 1200 pixels . Therefore, if the image you are using is not suitable, the preview result may not be quite right.

4. Do Clear Cache

If the preview that appears is not what you expected, there could be a cache problem. Therefore, first try clearing the cache, either on WordPress or on Facebook. Here’s how:

4.1. Clear Cache in WordPress

If you are using WordPress, clearing cache can be done easily using a plugin. Some of the plugin options are: W3 Total Cache, WP Super Cache, WP Fastest Cache .

Make sure you have installed the desired plugins. To do this, go to the WordPress dashboard> Plugin > Add New . Then type the name of the plugin, then Install and Activate .

Here’s how to clear cache using the three plugins:

W3 Total Cache

From the WordPress dashboard, click the Performance menu . On the W3 Total Cache settings page , click empty all caches . After a few seconds, the page will reload, and your cache will be cleared.

Open the WordPress dashboard and select Plugin. After that, click Add New , and search for WP Open Graph in the search bar. Once you find it, click on the Install Now button . Then do the activation.
